Synchro / Resolver Measurement (S/D) (R/D)

NAI's Smart Function Modules provide uniquely flexible, mix & match customization options for use with our COTS hardware. Learn More

Modules SD1, SD2, SD3, SD4, and SD5 are NAI’s latest generation Synchro/Resolver–to-Digital Modules. These multichannel, programmable, isolated input modules are used on our Multifunction Embedded I/O Boards, Rugged Systems, and Single Board Computers (SBCs) offered in OpenVPX, cPCI, VME, and PCI/PCIe configurations.

Modules SD1 – SD5

Synchros and Resolvers are transformer-type voltage/current transducers that convert a shaft or other rotating device's angular position and/or velocity to a multi-wire AC electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Resolver-to-Digital or a Synchro-to-Digital converter is used to convert these signals to a digital output corresponding to the shaft angle and/or velocity.

The SD1 - SD5 modules cover the range of excitation voltages/frequency, include extensive field-parameter programmability, and provide a full operating envelope choice for interfacing to virtually any type Synchro or Resolver. They feature background wrap-around self-test capability, and most platforms support an optional, programmable AC excitation supply. In addition to state-of-the-art technologies, Type II servo loop processing techniques, and specialized design algorithms, the modules include many other useful applications features such as excitation loss detection, and excitation voltage and frequency measurement. Operating voltages between 2 - 90 VL-L and reference voltage/frequency between 2 - 115 VRMS or 47 Hz - 20 kHz can be specified. Individual excitation inputs are supplied for each channel.
